When selecting a Storage Group and right-clicking on it, the interface will present the operator with a number of options. These options allow the administrator to perform operations on the entire storage group.
This option, which is the default if you double-click on a Storage Group, will redirect to the Platform Spaces screen and list all of the Platform Spaces on that storage group.
Utilizing the built-in LTO tape sub-system of Platform, the Backup Storage Group option allows the user to copy data from the Storage Group to tape. The operator has the option of running these backups as Full or Incremental. See the details of running Backups in the Tape section of this manual.
Snapshots allow administrators to set up Time Machine like versions of information on the Storage Group. See the Storage Group Properties section below to enable Snapshots. As noted below, Snapshots can only be enabled on true Platform Storage Groups, not additional 3rd party attached storage.
The View snapshot option allows the operator to open a window to view Snapshots of particular Platform Spaces. The operator will first choose a Platform Space to see all of the snapshots for that Platform Space.
After selecting a Platform Space, the operator will be presented with a list of Snapshots for that Space.
By clicking on the ‘Dismounted’ URL, the operator can mount the Platform Space as it was when the snapshot was taken. The workstation will open a simple file browser (Apple Finder or Windows Explorer) and show the Platform Space as it was previously. This allows an operator to recover accidently deleted files or restore files of a previous modified version.
Storage Group maintenance performs a series of optimization tasks on a storage group to insure its best performance for video streaming. When this maintenance process is run frequently, it will only take a few minutes even for very large (64TB – 96TB) groups. However, if it is many days, weeks or months between maintenance operations, the process can take hours or even days. Therefore, it is best to schedule maintenance for a daily operation.
Users can be using the Platform System when the maintenance task is run and it will not affect their ability to perform operations. However, as a rule of thumb, Storage Group Maintenance can impose a 30-50% penalty on system storage performance for that particular group.
Storage Group maintenance by default is set to run nightly at 10:00 PM. However, this schedule can be changed by the administrator by right-clicking on the Storage Group and selecting the start time and day(s) of the week. The administrator can also turn off maintenance by de-selecting the ‘Enabled’ checkbox.
Once the maintenance task is scheduled, it is listed in the Task screen under ‘Maintenance’ operations. Please see the Task Screen for more details on how to see the results of maintenance per storage group.
The Mirror command provides the ability to create a continuous backup of one storage group to another storage group or Platform Space within a Storage Group. Mirror operations check the source Storage Group every 60 seconds for changes. When changes are encountered, the updated files will be copied to the Destination Storage Group.
To set up a Storage Group Mirror, the administrator will right-click on the Storage Group and select ‘Mirror To’. The menu system will then display a list of Destination Storage Groups that can be selected.
After selecting a destination Storage Group, the administrator has the option of selecting the root of the Storage Group or a Platform Space within that Storage Group.
By clicking on the ‘Mirror’ button the system will then submit a task to the task service that will start the mirror copy. The Mirror copy task will run indefinitely until it is stopped by an administrator.
Speed – The Speed option allows the operator to choose from Slow, Medium or Fast depending on how much storage bandwidth the user wishes to use. Generally, slow will use 25% capacity, Medium (the default) will use 50% and Fast will attempt to use 100% of the possible storage system speed.
Schedule - The scheduling of a task can be done immediately or for a future date. This is the time the mirror will begin copying for the first time. See task scheduling options for more details.
Note: The destination of a Storage Group Mirror will have all data overwritten or erased. Please be careful to insure that the destination location selected is correct before proceeding.
This option is used to reset the security permission on a Storage Group. This is an option that is not normally used in daily operations of the Platform it has the effect of “Stripping Permissions” on the Storage Group back to the default. After selecting this option, the system will bring up a question confirming that the operator wishes to proceed:
This procedure should only be used when the administrator wants to clean out all the permissions on a particular storage group and start over. If the operator answers yes, the system will bring up a window allowing the operator to schedule the Storage Group Reset.
This window has the option to start the process immediately or to schedule it at a future time. There are also two additional options that can be used:
Reset Platform Spaces on a Storage Group – This has the effect of running a Platform Space Reset (see below) on every Platform Space that is stored on the Storage Group. This feature is particularly valuable when resetting a storage group. If you do not choose this feature, then any user that previously had access to Platform Spaces on this Storage Group will no longer have access to their volumes until the Platform Spaces have been reset.
Reindex Platform Spaces – This option will perform an asset management re-index of all the data within Platform Spaces that have been set to be indexed.
After the operator has clicked the ‘Reset Storage Group’ button, the system will schedule the reset into the task system and it can be monitored from that screen.
Reset Platform Spaces on a Storage Group- This has the effect of running a Platform Space Reset (see below) on every Platform Space that is stored on the Storage Group. Once the operator clicks on the option, a scheduling window will appear allowing the operator to choose to run it immediately or schedule the reset for a future time. The operator will also have the option of Re-indexing all the Platform Spaces on the storage group.
This option should only be used if you suspect file corruption or index corruption on the storage group. The option has the effect of running a windows repair-volume (chkdsk) on the specified storage group. The system brings up a dialog screen and requires the operator to enter the administrator password. This is the password of the Admin user on the Platform.
After the validation is complete, the system will allow the operator to schedule the repair immediately, or for a future time specified.
Please note: After a repair operation starts, all Platform Spaces on the Storage group will be taken offline until the repair operation is completed. This could have the effect of causing users to lose data on files that are currently open. Do not perform a Repair Storage until all users have logged off of the system. You can validate the all files are closed by checking the Open Files Screen.
The RAID Integrity option is used to check the file system at the level of the RAID structure. It is not normally used or necessary in daily operations. The RAID integrity check is started within the RAID controller software and can run for many hours. This option can be scheduled to run immediately or at a future time and date as desired.
Once it is scheduled, the operator can monitor the percentage complete by clicking on the Storage Group Properties options.
If issues with the RAID structure are found, the system will automatically attempt to repair them. Users can continue to use the system while RAID Integrity is running. Normally it will not significantly impact the performance of the Storage Group while it is running.
When selecting Storage Group Properties option, the system brings up the Storage Group Properties window and displays key information about the Storage Group. Based on the type of Storage Group, not all information is available.
The first tab, listed as properties, shows the basic information about the Storage Group including the File System type and sector size. The system also shows key information about some of the functions supported by this storage group type.
Rename Storage Group: This screen also shows the Current Name of the Storage Group and allows the Administrator to Rename the Group by typing in a new name. After the new name is entered, the operator will press the Okay button to rename the group.
Considerations for Renaming a Storage Group: It is critical to note, that when a Storage Group is renamed, the asset management database for all entries in that storage group will become invalid and all Platform Spaces on the Storage Group must be re-indexed.
If the operator answers Yes to this question, the system will proceed with renaming the storage group and it will start a task in the task system to re-index all Platform Spaces on the Storage group. It is critical to note, that any Platform Spaces that have been Removed from the Storage Group will not be included in the re-index process.
Performance: The Performance option only appears on native Platform Storage Groups and allows the Administrator to change the performance characteristics of the Storage Group. The options include:
Read: Favors streaming read performance. This is the default and is the best for standard video editing and streaming environments.
Write: Favors ingest or multiple update performance. Best for users with significant ingest requirements (loading data onto the Storage Group).
Mixed: Supports a combination of reads and writes. Best for environments when users will typically be doing both reading and writing to the disk system at the same time.
Snapshots allow administrators to set up Time Machine® like versions of information on the Storage Group. This feature will cause the system to take “snapshots” or moments in time of the storage system. These are stored on the Storage Group itself and the information is available later by mounting the Platform Spaces within the snapshots.
Snapshots are only available on Native Platform Storage Groups.
By clicking on the Snapshots tab in the Properties screen, the Administrator can enable or disable Snapshots on the Storage Group. The ‘Enable Snapshots’ checkbox, when checked, will open configuration options for the administrator to configure snapshots.
If snapshots are enabled, and the administrator deselects the checkbox, the system will ask the administrator to validate the selection. If they answer yes to this question, the system will remove all data associated with existing snapshots.
The administrator will configure the snapshots for the Storage Group by selecting the following:
Space to Allocate: This indicates the total space on the Storage Group to use for the storage of the snapshots. Snapshot histories are very efficient and the system only copies ‘changes’ with each snapshot so you do not need to allocate a huge amount of space if there is minimal data change on the Storage Group.
Max Snapshots to Keep: This indicates the number of ‘versions’ or snapshots to be taken before prior snapshot versions are deleted. If you select 5, as in the example, upon the 6th snapshot, the Platform will automatically delete the 1st.
Schedule: The administrator has the option of setting a start and end time or the “window” when snapshots will be taken. Included in this is the days of the week. The last parameter is how long in between snapshots. The example above shows that the system will take a snapshot every hour, however, you can set this to perhaps 1,439 minutes (60*24) and the system will take only one snapshot per day.
Most storage groups can be connected to the Platform without powering down the unit. SAS or Fibre channel units are the exception and when connecting this type of storage, a power down before connecting is strongly recommended. However, USB, Firewire, eSata, and Thunderbolt can be connected while the Platform is operating.
When a new storage group is connected to the system, if the system has permissions to the drive, the Platform will automatically bring the device online. The new storage group will automatically show up in the storage group screen. This polling process occurs every 5 minutes.
The Administrator also has the option of clicking on the "Scan for Attached Drives" button.
This function will force the system to go out and look for new storage groups immediately and bring them online. After pressing the scan button and when a new Storage Group is found, the Administrator will receive a dialog box describing the results.
When connecting Thunderbolt Storage to the Platform, you will need to ensure that the Platform System has the appropriate Windows Driver for the Thunderbolt Device you are connecting. Many Thunderbolt drivers are pre-loaded onto the system. However, not all manufacturer devices have been pre-set or configured.
Once you have connected your device to the Platform, if it does not show up in the Platform interface after performing a ‘Scan for Attached Drives’, you will need to login to the Platform Server Console and check the drivers for the device you are attaching. If you are unfamiliar with loading drivers into a Windows System, please contact the ProMAX Support Team for assistance.
The First Time a Storage Group is Attached
The first time a Storage Group is connected to the system, if the storage group uses a permissions system, you will need to run a Storage Group Reset which is found in the right-click menu of each storage group. This is also true if you reinstall the Platform software or move a storage group to a Platform Server on a different domain.
When a Storage Group is removed from the system, all files and data from that Storage Group are no longer available to operators using the system.Although because of the integrated catalog and asset management system, if Platform Spaces on the Storage Group were indexed before the Storage Group was taken offline, operators can still perform searches on files on that storage group.
